GENERAL DESCRIPTION

The patent-pending ACT8342 is a complete, cost

effective,

highly-efficient

ActivePMUTM

power

management solution that is ideal for a wide range

of portable handheld equipment. This device

integrates one PWM step-down DC/DC converter

and two low noise, low dropout linear regulators

(LDOs) in a single, thin, space-saving package.

This device is ideal for a wide range of portable

handheld equipment that can benefit from the

advantages of ActivePMUTM technology but does

not require a high level of integration.

REG1 is a fixed-frequency, current-mode PWM

step-down DC/DC converter that is optimized for

high efficiency and is capable of supplying up to

350mA output current. REG1’s output is available in

a variety of factory-preset output voltage options,

and an adjustable output voltage mode is also

available. REG2 and REG3 are low noise, high

PSRR linear regulators that are capable of

supplying up to 80mA and 150mA, respectively.

The ACT8342 is available in a tiny 3mm

× 3mm

16-pin Thin-QFN package that is just 0.75mm thin.
